Erebus - Level 6: Erebus Station

Erebus - Level 6: Erebus Station is the sixth level of Doom 3: Resurrection of Evil. The player must first navigate an outdoors area, then fight through sewer tunnels with the help of a sentry bot, and finally, win a boss fight against the Berserk Hunter, after which the player acquires the Berserk power for the Artifact. The cacodemons and revenants return in this level.

Summary
The first area the marine goes through is the surface area, where he has to swiftly find the ladder to the catwalk and run to the nearby airlock, contending with cacodemons and vulgars along the way. Once inside, the marine encounters Ryden, a survivor who tells him that he has sent a sentry bot down into the tunnels and that it's still there. He says the marine should find it and follow it to the exit from tunnel and reach the monorail station there. The marine then proceeds deeper into the facility, fighting his way through several rooms and corridors. On his way he can find an optional armory, the access to which is granted by picking up a PDA located nearby. Eventually, the marine enters the tunnels and meets the sentry bot. Together they fight their way through tunnels, filled with all sorts of monsters, until they find the exit, where the sentry bot becomes dormant.

The marine enters the monorail station via a maintenance shaft. However, something isn't right: the station is filled with corpses and hellish residue, and it's pretty spacious. It's almost as if there's going to be a boss fight. And sure, once the marine calls for the monorail car, the wall behind him breaks and the Berserk Hunter appears! This Hunter has the ability to enter berserk mode and perform very quick and long leap attacks at the player. During its berserk mode, its heart is exposed and is the Hunter's weak spot. After taking some damage, the Hunter will enter its "calm" mode, becoming temporarily immune to damage and launching a few fireballs at the player, before becoming berserk again. After dealing enough damage to the Hunter's heart, it becomes defeated and burns away, imbuing the Artifact with a new power - Berserk, which greatly increases the damage of his attacks while the Artifact is active, especially his fists.

The marine then takes the monorail train to the Phobos labs.
